Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547310, here are decompositions:

7 + 31547303 = 31547310
13 + 31547297 = 31547310
23 + 31547287 = 31547310
29 + 31547281 = 31547310
43 + 31547267 = 31547310
79 + 31547231 = 31547310
101 + 31547209 = 31547310
107 + 31547203 = 31547310

Showing the first eight; more decompositions exist.
